Fig. 4: Comparison of SEM images of polar bimodal polyethylene samples prepared by co-anchored catalyst and mixed heterogeneous catalyst after incorporation of polar monomer.
From: A co-anchoring strategy for the synthesis of polar bimodal polyethylene
These bimodal polymers in the first row were prepared by co-anchored catalyst Ni2/Ni3-MgO, and those in the second row were prepared by mixed heterogeneous catalyst Ni2-MgO/Ni3-MgO. Incorp. (Incorporation) ratios of comonomers were determined from 1H NMR spectra. The characterization data of these polymers are listed in Supplementary Information Table 4.
